Before selecting the best electric motor for your business, one must consider several key factors related to your specific requirements and the motor’s capabilities. As part of our commitment to keeping you up and running, the Hi-Speed team has compiled a list of the most common factors to consider, along with brief explanations, to help you select the right electric motor for your business or application.

Voltage
The power source connections available in your facility must match the motor’s voltage requirements. In most cases, smaller electric motors usually require only a wall socket or J-box protected by a standard breaker. However, larger industrial motors usually require an electric sub-panel or an inline disconnect device to connect to the power grid.
Capacity and Size
The right electric motor must provide the necessary torque without generating heat that exceeds the internal wiring insulation rating. Smaller motors are ideal when the motor will be used in various locations throughout the facility. Larger motors are suitable for permanent installations that power larger accessories such as pumps or conveyors.
Electric Motor Speed
Some electric motors are better suited for high-speed applications, while others are better for low- to moderate-speed needs. The motor’s design, construction, and internal parts determine the motor’s maximum and minimum speed. Specific applications may require adjustable speed controls to assist with managing rotation and torque, while accommodating changing load sizes or weights.
Electric Motor Torque
Torque is required during startup and acceleration to move loads at a specific rate within a predetermined timeframe. Insufficient torque forces the motor to work harder, resulting in excessive power consumption and higher utility bills over the motor’s lifespan. The goal is to ensure the motor can safely power the connected equipment without overloading the motor bearings, shafts, insulation, or electronics.
Electric Motor Orientation
Horizontal AC electric motors are typically used for conveyors, compressors, pumps, and other equipment that require reliable and continuous power to maximize efficiency and productivity.
Vertical AC electric motors are designed and built to withstand thrust loads, as well as the weight and movements of rotating parts. These specialized features allow them to work efficiently in more hostile environments.
Electric Motor Enclosure
The operational conditions found at your facility will dictate which type of enclosure should be used for maximum motor protection. Carefully examine the adjoining areas to determine if the motor will be exposed to dirt, dust, debris, moisture, or excessive heat. This will help you determine which enclosure option is best suited to your needs. For example, stainless steel castings are typically required to protect against spills or corrosion for food and beverage locations.
Duty Cycles
Most electric motors and their connected devices either run continuously or for short periods. The longer the anticipated run time, the higher the duty cycle required to avoid power loss. The operational temperature must also be considered to prevent overheating during long or short operational cycles.
Operational Life Span
A motor’s operational lifetime can directly impact the lifespan of any connected tools or equipment. High-quality motors typically have a better ROI, lower maintenance costs, and last longer because they utilize superior internal components or assemblies. Regular maintenance and inspections can keep you running at peak performance across the motor’s lifecycle.
More Electric Motor Factors
In addition to the points outlined above, different industries or applications may require encoders & sensors, rotational controls, and climate protection factors as part of the motor selection process. Regular maintenance costs should also be a significant factor in the decision-making process.
